if you know the circumference of your 17" inch wheel and can get the same measurement on a 16" wheel, you can compute the percent difference. let's say the 16" wheel is 90% of the 17". . then the 3.55s on your truck would be about the equivalent of 3.20 compared to a truck with 16" wheels (3.55 x .9)

I wouldnt think wheels would make any difference on gearing, just what tires are on the wheels. The OD of the tires is all that matters for gearing.</font>

purposes? Or is there a standard - maybe you just have the driveshaft/axle ratio to go by?
